This invention relates to improvements in cartons or containers.

In general, a carton or container embodying the invention comprises abody part and a cover part, the body part being provided with an accessor discharge opening preferably at one end and the cover part with adispensing opening, preferably located at a lateral side, the body partand the cover part otherwise being devoid of opening, the aforesaidbeing combined with suitable means for eilecting a restricted movementof the cover part relative to the body part to afford the dispensing ofthe contents, but maintaining at all times the cover part and the bodypart in relative telescopic engagement.

Embodiments of the invention are preferably formed of relatively stisheet material, such as paper stock, notably of cardboard, but may beformed of other sheet material having suitable characteristics forattaining the objects of the invention.

In general, the contents of the carton or container are dispensedthrough the dispensing opening of the cover part when the cover part hasbeen moved to its maximum, i. e., restricted position in direction awayfrom the major portion of the body part. The telescopicengagement-restricting and maintaining means may be arranged to aiford asnap action in the movement of the cover part to its open and closedpositions, respectively. The cover part may also be providedwith stoppermeans whereby the access or discharge opening of the body part is sealedagainst leakage of davor-imparting and/or aroma-imparting constitutentsof the material contained in the carton or container, also againstsifting of contents, sealing against air, and the like.'

Fig. 12 is a plan view of a blank suitable for forming a body part ofthe embodiment of Figs. '7 through 10 of integral construction, anintermediate portion of the blank being broken away for reduction ofshowing.

Referring to the embodiment shown -in Figs. 1 through 4, the same asshown comprises a body part 20 and cover part 2|. The body part 20 isshown as provided with an access or discharge opening, indicated at 20a,see Figs. 3 and 4, disposed at its upper end as positioned in Figs. 1through 4. The body part 20 otherwise is imperforate. y

As illustrated, the body part is of rectangular cross-section, but maybe of any desired polygonal or other cross-section. The bottom 20h ofthe body part 20 is closed; as illustrated, the bottom Zlib is formed tobe closed pursuant to conventional practice.

The cover 2| is provided with a dispensing opening 2|a which may be ofany conguration and located as desired'in accord with the invention. Asillustrated in Figs. 1 through 4, the dispensing opening 2|a is disposedon a lateral side of greater dimension of the cover part and closelyadjacent the closed end 2lb of the cover part.

The cover part 2| is associated with the body part 20 to restrictmovement of the cover part in direction away lfrom the major portion ofthe body part (to thereby dispense the contents as referred to morefully hereinafter) and to retain the cover part 2| at all times intelescopic engagement with the body part adjacent the portion thereofproximate the access opening 20a of the body part. Any suitable meansfor carrying out such function and relationship may be em-Y ployed. Ason suitable means for carrying out such function and relationship, asillustrated in Figs. 1 through 4, the restricting and retaining meanscomprising one or more extensions 22 o! relatively sti material one endoi' each such extension projecting from or otherwise is secured to thematerial of the sides of the body part 2l and adjacent its accessopening 2.a. the other end of each such extension being secured to theinner face of the top 2lb of the cover part. In the embodimentillustrated. two such extensions 22, 22, are employed, To enhance theyieldability of such relatively stir! extensions 22, 22, the same may beweakened at portions thereof, such as the illustrated one or more scorelines, indicated at 22a, preferably disposed proximately centrally andextending transversely of the longitudinal dimension of the extensions22, 22.

It is noted that the dispensing opening 2|a of the cover part 2| isdisposed in the indicated lateral side of the cover part 2i to secureclosure of the dispensing opening 2 ia and therewith of the accessopening a oi the body part 2| when the cover part 2| and the body part2l are in maximum telescopic engagement, i. e., when the cover part hasbeen moved to the limit toward the major portion of the body part. Uponrelative movement of the cover part in direction away from the majorportion oi the body part 2l under restriction by the one or moreextensions 22, the dispensing opening 2|a is opened to greater andgreater extent and is opened to maximum extent upon full movement of thecover part 2| in the stated direction.

Figs. 1 and 3 illustrate the closed position of the dispensing opening2|a and Figs, 2 and 4 the full open position of the dispensing opening2|a. Regulation of the eifective area of opening of the dispensingopening 2in is attained by 1ocating the same with relation to themarginal line indicated at 23a, i. e., the spacing of the proximate edgeof the dispensing opening 2|a from the marginal line 23a, see Fig. 5,indicating the intersection of the applicable lateral side oi the coverpart 2| and the closed end 2lb of the cover part 2|.

Embodiments of the invention typified by Fig 1 through 4 may be chargedby charging the tobe-dispensed contents through the opened bottom 2lb ofthe body part; the bottom 20d is thereafter closed.

The blanks illustrated in Figs. 5 and 6 indicate suitable means forforming the cover part and the body part of the embodiment shown inFigs. 1 through 4 of integral construction. Panels of these blankscorresponding to the parts of the embodiment shown in Figs. l through 4bear like reference characters. It will be observed also that the panels23 respectively extending from the material of the two largerdimensioned and the two smaller dimensioned lateral sides of the coverpart 2| serve to close the top 2lb of the cover part. The panel 24combines with the extreme right hand panel of the cover part 2| to aiordoverlapping glue areas for attaining the hollow configuration of thecover part. The panels of the blank shown in Fig.' 6 indicate similarlythe formation of the body part 2l of integral construction. Fig. 6 alsoshows the extensions 22 as formed integral with the material of panelsforming two oppositely positioned lateral sides of the body part 2|I.The score lines 22h serve as hinges for the respective extensions .22,upon securement of the end portions of the extensions 22 to the innerface of the top 2 Ib o! the coverpartasbyglueorthelike. v'lihescoralines22s enhance the yieldabiiity of the respective extensions 22. Fig. 6shows also extensions 2l projecting from the indicated panels of thelateral sides of the body part 2l which serve as means for closing thebottom 2lb of the body part 2l. The extension 2l cooperates with theextreme right hand panel oi' the body Part 2l for anording overlappingglue areas for attaining the hollow configuration o! the body part 2l.

I'he embodiment typliied by Figs. 7 through 10 corresponds generally tothe embodiment of Figs. 1 through 4, and corresponding parts areindicated by like reference characters. The embodiment of Figs. "lthrough 10 illustrates the locating of the dispensing opening 2in at alateral sidefof the cover part 2| of lesser dimension. The embodiment ofFigs. '1 through 10 commises the further features of locating on the oneor more extensions I22 the score line 22e-in lieu of the above referredscore line 22a-to eiiect a snap" opening and closing action of the coverpart 2| relative to the body part 2l. Speciilcally by locating the 22escore line transverseb ot the direction oi' length of each extension 22and and at a spacing greater from its end which is secured to theindicated panel oi' the lateral side of the body part 2l as comparedwith its spacing from its end which is secured to the top 2lb ot thecover part 2|, an eccentric lever action is produced, thereby causing asnap" action in the to and iro movements of the cover part relative tothe body part.

The embodiment shown in Figs. 7 through 10 features also the embodimentof a stopper eiement 21 formed either integral with or attached to theend portions of the extensions 22 which are secured to the inner falceof the top 2lb of the cover part; in the illustrated embodiment suchstopper element 21 is shown formed integrally with the extensions 22.Buch stopper element 21 serves, when the cover part is in relativeclosed position with regard to the body part 2l, to seal the accessopening '2.a o! the body part 2l, for purposes of air-sealing theclosure and safe-guarding against loss of iiavor or aroma, andprecluding sifting of contents, and like purposes.

The blanks indicated in Figs. 11 and 12 illustrate one method of formingthe body Dart 2l and cover part 2| of integral construction, inclusiveof their respective closing end panels and of the ex tensions 22; likeparts are indicated by like reference characters.

It will be observed with regard to the blank shown in Fig. 11 that thedispensing opening 2|a formed in a latral side of the cover Dart 2| maybe open-ended when the blank 2| is in projected, i. e. plan position.Fig. 1l illustrates also the employment of but two panels 22, projectingfrom the indicated :two panels of oppositely disposed lateral sides ofthe cover part 2|; such arrangement is advantageous in cc-action withthe thereto glued" end portion of the extensions 22, see Fig. l2, fordually closing the end 2lb of the cover part 2| and forming the stoppermeans 21, as weil as securing the concerned end portions of theextensions l22. The stopper means 21 may comprise suitable material suchas cork as additional stopper means, suitably secured to the stated endportions of the extensions 22,

As appears irom -the aforesaid, the body part and cover part and theirrespective associated parts may be formed of any suitable resilientstil! sheet material; sheet material such as cardboard or like paperstock is preferred.

Whereas I have described my invention by reference to specific formsthereof, it will be understood that many changes and modifications maybe made without departing from the spirit of the invention.
